“…According to the literature [8,[26][27][28][29][30] and our experimental results, it is believed that MoS 2 and WS 2 IF nanostructures are formed in vapor, and the growth is dominated by the vapor-solid (VS) mechanism. By heating the reactants directly to 850 8C, the chlorides (MoCl 5 or WCl 6 ) and S quickly evaporate and simultaneously react.…”

“…Reaction mechanism: Reported strategies for the synthesis of sulfides, [8,26,[28][29][30] especially the reactions between chlorides and a mixed gas of H 2 S and H 2 , [8,28] gives us a good understanding of the reaction mechanism of MoCl 5 /WCl 6 and S. In the well-known reaction of MoCl 5 and H 2 S/H 2 , H 2 is used as the additional reductant [Eq. (1)].…”

Large-scale MoS2 and WS2 inorganic fullerene-like (IF) nanostructures (onionlike nanoparticles, nanotubes) and elegant three-dimensional nanoflowers (NF) have been selectively prepared through an atmospheric pressure chemical vapor deposition (APCVD) process with the reaction of chlorides and sulfur. The morphologies were controlled by adjusting the deposition position, the deposition temperature, and the flux of the carrier gas. All of the nanostructures have been characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). A reaction mechanism is proposed based on the experimental results. The surface area of MoS2 IF nanoparticles and the field-emission effect of as-prepared WS2 nanoflowers is reported.

“…The metathesis reactions occur rapidly such that all of the enthalpy released is essentially used to heat up the solid products, usually raising the alkali halide near or above its normal boiling point and accordingly recognized as adiabatic in nature. The real driving force for metathesis reactions is from the formation of thermodynamically stable salts such as NaCl [21][22][23].…”

Applying a metathesis approach (MCl 2 •xH 2 O+Na 2 SnO 3 •xH 2 O→MSn(OH) 6 +NaCl+xH 2 O), Schoenfliesite-type materials with general formula MSn(OH) 6 (where M=Ca, Cu, Mg, Mn or Zn) were synthesized at room-temperature. The high lattice-energy of the by-product alkali halide NaCl drives the reaction in the forward direction leading to the formation of the desired materials. The materials synthesized were characterized by powder X-ray diffraction (XRD) and scanning electron microscopy (SEM) to elucidate structural and micro structural features.© Versita Warsaw and Springer-Verlag Berlin Heidelberg.

followed by dropwise addition of 338 mL of H 2 O while stirring vigorously. The homogeneous mixture was purged with nitrogen and 5 mL of 1 M Cd(NO 3 ) 2 ×4H 2 O was then added via a microliter syringe to 10 mL of the stirred reverse micelle solution. 5 mL of 1 M Na 2 S was slowly added and the solution was stirred for 20 min. Particle sizes were determined by UV-vis spectroscopy.Mechanical testing was performed on single fibers of the inorganic-silk composites, which were attached to the twin arms of a custom-built stress± strain gauge using cyanoacrylate adhesive, and hysteresis cycles and breaking strength measurements were performed at ambient conditions of 29 C and 34 % relative humidity. The measured stress was normalized using fiber diameters determined by SEM (mean diameter = 3.1±0.5 mm). The custom stress±strain gauge consisted of a FORT 10 force transducer (World Precision Instruments) and a Pen Motor Assembly (Hewlett Packard).
